Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 177,475,775, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 177,475,775 | |
| -1 | -177,475,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,475,775.
Example:
1 x 177,475,775 = 177,475,775
and
-1 x -177,475,775 = 177,475,775
Notice both answers equal 177,475,775
With that explanation out of the way, let's continue. Next, we take the number 177,475,775 and divide it by 2:
177,475,775 ÷ 2 = 88,737,887.5
If the quotient is a whole number, then 2 and 88,737,887.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 177,475,775 | |
| -1 | -177,475,775 |
Now, we try dividing 177,475,775 by 3:
177,475,775 ÷ 3 = 59,158,591.6667
If the quotient is a whole number, then 3 and 59,158,591.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 177,475,775 | |
| -1 | -177,475,775 |
Let's try dividing by 4:
177,475,775 ÷ 4 = 44,368,943.75
If the quotient is a whole number, then 4 and 44,368,943.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 177,475,775 | |
| -1 | 177,475,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 73 | 155 | 365 | 775 | 1,825 | 2,263 | 3,137 | 11,315 | 15,685 | 56,575 | 78,425 | 97,247 | 229,001 | 486,235 | 1,145,005 | 2,431,175 | 5,725,025 | 7,099,031 | 35,495,155 | 177,475,775 |
| -1 | -5 | -25 | -31 | -73 | -155 | -365 | -775 | -1,825 | -2,263 | -3,137 | -11,315 | -15,685 | -56,575 | -78,425 | -97,247 | -229,001 | -486,235 | -1,145,005 | -2,431,175 | -5,725,025 | -7,099,031 | -35,495,155 | -177,475,775 |
